PLATE 3 



EXPLANATION OF FIGURES 



12 Photograph of graft LN 44, taken twenty-six days after the operation. 

 The only change up to death, on the 127th day, was a slight increase of prolifer- 

 ated tissue at the ends. X 3. 



13 Photograph of graft LN 64, taken eleven days after the operation. The 

 darker region surrounding the central opening is due to an abundance of melano- 

 phores there. X 3. 



14 Photograph of graft DN 2, taken fourteen days after the operation. 

 Proliferation has begun and is easily seen at the corners of the graft. The irreg- 

 ularity of the proliferated tissue is noticeable. X 3. 



15 Photograph of graft LB 9, taken four months after the operation. Slight 

 amorphic regeneration is shown. No absorption occurred and the characteristic 

 features of tail skin were preserved. X 3. 



16 Photograph of graft LN 78, taken three months after the operation. Pro- 

 liferation from both ends, absence of absorption, and preservation of tail-skin 

 characteristics are the features of this graft. Refer to figure 11. X 3. 



17 Photograph of graft LN 104 taken three months after the operation . The 

 back-skin graft over the eye has become almost indistinguishable from the sur- 

 rounding skin, but the tail-skin graft has proliferated and preserved its charac- 

 teristics. X 3.
